The working principle of the present embodiment is: the secret key of asymmetrical encryption algorithm of the present invention is divided into private spoon and public affairs
Spoon knows that its private spoon can generate public spoon by calculating, and in turn, knows that its public spoon is cannot to generate private spoon by calculating；It is only single
To can be with, rather than it is two-way be ok, therefore have asymmetry.The data that asymmetrical encryption algorithm includes private spoon encryption only have public affairs
The characteristic that spoon can be decrypted, the only private spoon of the data of public spoon encryption can be decrypted；So application upper combination secret key asymmetry feature with
Encryption and decryption feature, individual hold private spoon, and public spoon is made known to the world, so that it may accomplish the thing for being similar to manual signature or impressing；It is assorted
? because only that holding the data of people's encryption of that private spoon, that private corresponding public spoon of spoon could be decrypted, without second people
Hold that private spoon, so this is equivalent in former number in addition to his (she/it) without second people can encrypt such data
According to above having signed the name marking.
The safety of asymmetrical encryption algorithm: the most weak place of this kind of algorithm is just in the protection of private spoon, and on business spoon is public
Open, if can it is public spoon is counter extrapolates private spoon, that all bad thing can be done, the entire algorithm so the safety of key-encryption algorithm is determined
Safety.Key algorithm will be always based on based on a problem mathematically, such as RSA: give two prime number ps, q
It is easy to be multiplied and obtains n, and factorization relative difficulty is carried out to n；ECC elliptic curve is based on: K=kG [wherein K, G
For the point on Ep (a, b), k is the integer less than n (rank that n is point G)] it is not difficult to find that given k and G, according to Adding law, meter
K is calculated to be easy to；But given K and G, asks k with regard to relative difficulty.It is said herein it is difficult be not cannot, be that there is presently no numbers
It learns formula directly to calculate, but the calculating speed of computer is quickly, can be calculated by the quick-fried power mode of exhaustion, with calculating most fast at present
For cracking, as long as being of convenient length for secret key is longer, need to crack the time with up to a million years.Therefore, it is currently used not
Symmetric encipherment algorithm is safe.
At the deficiency of asymmetrical encryption algorithm: the calculating power of encryption, low efficiency, therefore encrypted plaintext cannot be too long,
The content being namely digitally signed cannot be too long.Otherwise efficiency is very too low.In order to solve the problems, such as that signature contents cannot be too long, this
Digital digest algorithm (common to have MD5, SHA1, SHA256) has also been introduced in invention.Its principle is such as: such as several very big just whole
How number, quickly distinguish them, simple method takes the units (i.e. mould is with 10) of its most position；It is likely that such point-score meeting
There is duplicate value to cause to distinguish, is to change one the reason is that this differentiating approach is too simple and result set is too small (only 10 numbers)
As soon as kind of method and result set do it is big this, do not allow to be also easy to produce duplicate value.Digital digest algorithm is suitable with this, only method
Complicated and result set is bigger, goes abstract article and data etc. are all difficult to produce very much duplicate value with common digital digest algorithm.
Existing safety problem of signing is carried out with asymmetrical encryption algorithm merely: although the algorithm of secret key is currently safety
, cannot crack to obtain from front, but computer, mobile phone, server etc. calculate equipment still there are many security breaches hackers can
It can steal and arrive, if stolen to private spoon, be forged with private spoon past extremely big to oneself harmful digital signature, that holds private spoon not with regard to one
Moment calamity is beyond redemption！Hand will be fallen from the time certainly by solving this, to be given way and be arrived private spoon steathily and also do not forge past tense
Between digital signature, seek to make production figures signs be it is true, not so forge.Now relatively good method announces it
In record block on to block chain, being published to block chained record block has N parts of copies, and next record block is with having previous record block
The main informations such as the digital digest value of location and previous record block full content, when record block is recorded each signature and generated
Between equal main informations.If the content of change past some block of record block necessarily causes the change of its digital digest value, can
Lead to the difference with next record block number word digest value, if removing the previous block number word digest value of modification next record block again,
Its digital digest value of next record block and lower next record block be will lead to on not, all recording for whole block chain is needed with this
Block modification, puppet produces whole block chain again, but block chained record block has N parts of copies to spread to each piece of the whole world, can obtain again
Whole block chain that others is deposited oneself is not changed.Therefore the time recorded on block chain be currently it is safe, compensate for puppet
Make over signature the problem of.It is stolen for private spoon that the method for cancelling private spoon can be also issued on block chain, it is later right to be stolen private spoon
Oneself harmful forgery digital signature.
Therefore, in embodiments of the present invention, block chain of the present invention is the upgrading of asymmetrical encryption algorithm application,
So it has all characteristics of asymmetric cryptosystem, such as prevent from distorting as digital signature；Signature is issued on block chain, is had automatic
Timestamp effect label it is anti-tamper, have non-repudiation, and merely use asymmetrical encryption algorithm, have because private spoon leak forge
Past signature problem；And it can prevent artificial factor from the account being transferred to being caused to malfunction, push away duty mutually；Due to this hair
Bright warehouse enterprise is participated with the role of client application, is not needed modernization system energetically and is docked with platform gateway, so
Warehouse enterprise participates in simply, regardless of the IT development ability power of warehouse enterprise all may participate in wherein；The present invention can be embedded into greatly
Ancestor's cargo transaction platform is to support logistics links.
The foregoing description of the disclosed embodiments makes professional and technical personnel in the field can be realized the present invention.To these
A variety of modifications of embodiment will be readily apparent to those skilled in the art, general original as defined herein
Reason can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, the present invention will not
Be intended to be limited to the embodiments shown herein, and be to fit to it is consistent with the principles and novel features disclosed in this article most
Wide range.
